License from University of Nebraska Medical Center covers multiple low dose interleukin-2 (ld IL-2) combinations, including ld IL-2 + Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF); New data, viewable here, illustrate that the combination of ld IL-2 + GM-CSF results in a 4-6 fold synergistic increase in Tregs; License expands on Coya’s multi-pathway approach in identifying and combining immunomodulatory drugs with COYA 301 (Coya’s proprietary ld IL-2) that have been shown to be synergistic to enhance Treg function and simultaneously lower inflammation HOUSTON--(BUSINESS WIRE)-- Coya Therapeutics, Inc. (NASDAQ: COYA) (“Coya” or the “Company”), a clinical-stage biotechnology company developing multiple therapeutic programs intended to enhance regulatory T cell (Treg) function, has expanded and strengthened its patent estate beyond COYA 302, which is a combination of COYA 301 with CTLA-4 Ig. This license with UNeMed Corporation (UNeMed), the Technology Transfer Office of University of Nebraska Medical Center, covers the combination of COYA 301 with GM-CSF and additional immune analogues and provides a next generation approach with a novel combination to synergistically modulate and reduce inflammation. UNeMed will receive payments upon achievement of certain milestones and will be eligible to receive tiered low single-digit royalty on net sales. “We believe that COYA 301 is ideally situated to serve as a backbone drug in combination with other biologics that synergistically modulate the immune system and represent next generation approaches to treating inflammatory disorders, which are driven by complex and multi-factorial pathways. Enhancing Treg activity with COYA 301 in combination with GM-CSF and additional immune analogues creates yet another novel biologic combination in addition to Coya’s lead asset, COYA 302 and expands optionality and potential partnerships,” stated Arun Swaminathan Ph.D., Chief Business Officer. GM-CSF is a potent immune modulator known to promote Treg activities and dampen pro-inflammatory T effector responses, and ld IL-2 is a cytokine that enhances Treg function and numbers. Preclinical data (here) generated by the Gendelman laboratory at UNeMed demonstrated that the combination of ld IL-2 + GM-CSF generated a synergistic increase in Tregs in mice tissue, including in peripheral blood, spleen, and lymphoid cells. This included a 4-to-6-fold higher expression of Tregs in mice treated with the combination compared to treatments with either cytokine alone. Other markers that indicate a suppressive Treg phenotype were dramatically increased as well, including a 4-fold increase in CD25+CD127low cells and a synergistic increase in the percentages of CD25+CD4+ Tregs that express CD39+, ICOS+ markers, and GITR+. Michael Dixon, Ph.D., President and CEO of UNeMed, noted, “This agreement with Coya can potentially bring new therapies to patients suffering from neurodegenerative conditions. Coya’s foundation and progress in low-dose IL-2 research makes them an ideal company to leverage our findings to date.” About UNeMed Corporation UNeMed Corporation is the technology transfer and commercialization office for the University of Nebraska Medical Center.

About COYA 302 COYA 302 is an investigational and proprietary biologic combination therapy with a dual immunomodulatory mechanism of action intended to enhance the anti-inflammatory function of regulatory T cells (Tregs) and suppress the inflammation produced by activated monocytes and macrophages. COYA 302 is comprised of proprietary low dose interleukin-2 (LD IL-2) and CTLA-4 Ig and is being developed for subcutaneous administration for the treatment of patients with ALS. These mechanisms may have additive or synergistic effects. In February of 2023, Coya announced results from a proof-of-concept, open-label clinical study evaluating LD IL-2 and CTLA-4 Ig in a small cohort of patients with ALS conducted at the Houston Methodist Research Institute (Houston, Texas) by Stanley Appel, M.D., Jason Thonhoff, M.D., Ph.D., and David Beers, Ph.D. This study was the first-of-its-kind evaluating this dual-mechanism immunotherapy for the treatment of ALS. Patients in the study received investigational treatment for 48 consecutive weeks and were evaluated for safety and tolerability, Treg function, serum biomarkers of oxidative stress and inflammation, and clinical functioning as measured by the ALSFRS-R scale. During the 48-week treatment period, the therapy was well tolerated. The most common adverse event was mild injection-site reactions. No patient discontinued the study, and no deaths or other serious adverse events were reported. Patients' disease progression was measured using the ALSFRS-R scale, a validated rating tool for monitoring the progression of disability in patients with ALS. The mean (±SD) ALSFRS-R scores at week 24 (33.75 ±3.3) and week 48 (32 ±7.8) after initiation of treatment were not statistically different compared to the ALSFRS-R score at baseline (33.5 ±5.9), suggesting significant amelioration in the progression of the disease over the 48-week treatment period. Treg suppressive function, expressed as percentage of inhibition of proinflammatory T cell proliferation, showed a statistically significant increase over the course of the treatment period and was significantly reduced at the end of the 8-week washout post-treatment period. Treg suppressive function at 24 weeks (79.9 ±9.6) and 48 weeks (89.5 ±4.1) were significantly higher compared to baseline (62.1 ±8.1) (p<0.01), suggesting enhanced and durable Treg suppressive function over the course of treatment. In contrast, Treg suppressive function (mean ±SD) was significantly decreased at the end of the 8-week washout period compared to end-of-treatment at week 48 (70.3 ±8.1 vs. 89.5 ±4.1, p <0.05). The study also evaluated serum biomarkers of inflammation, oxidative stress, and lipid peroxides. The available data up to 16 weeks after initiation of treatment suggest a decrease in these biomarker levels, which is consistent with the observed enhancement of Treg function. The evaluation of the full biomarker data is ongoing. COYA 302 is an investigational product not yet approved by the FDA or any other regulatory agency. About Amyotrophic Lateral Sclerosis Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's Disease, is a rare neurological disease that affects motor neurons, the nerve cells in the brain and spinal cord that control voluntary muscle movement. About 20,000 people live with ALS in the United States and approximately 5,000 new cases are diagnosed every year. The disease is progressive, meaning the symptoms get worse over time. The functional status of ALS patients declines about 1 point per month on average, as measured by the Revised ALS Function Rating Scale1, or ALSFRS-R, a validated tool to monitor the progression of the disease. ALS has no cure, and the currently approved drug treatments provide limited benefit to patients. ALS is a type of motor neuron disease. As motor neurons degenerate and die, they stop sending messages to the muscles, which causes the muscles to weaken, start to twitch (fasciculations), and waste away (atrophy). Eventually, the brain loses its ability to initiate and control voluntary movements. Most people with ALS die from respiratory failure, usually within three to five years from when the symptoms first appear.2 About Frontotemporal Dementia Frontotemporal dementia (FTD) is the result of damage to neurons in the frontal and temporal lobes of the brain. Many possible symptoms can result, including unusual behaviors, emotional problems, trouble communicating, difficulty with work, or difficulty with walking. FTD is rare and tends to occur at a younger age than other forms of dementia. About 60% of people with FTD are 45 to 64 years old. FTD is progressive, meaning symptoms get worse over time. In the early stages, people may have just one symptom. As the disease progresses, other symptoms appear as more parts of the brain are affected. It is difficult to predict how long someone with FTD will live. Some people live more than 10 years after diagnosis, while others live less than two years after they are diagnosed. There is no cure for FTD, and no treatments slow or stop the progression of the disease.3 About Parkinson’s Disease Parkinson’s disease (PD) is a progressive brain disorder that causes unintended or uncontrollable movements, such as shaking, stiffness, and difficulty with balance and coordination. The most prominent manifestations of PD occur when nerve cells in the basal ganglia, an area of the brain that controls movement, become impaired or die. As the disease progresses, people may have difficulty walking and talking. They may also have mental and behavioral changes, sleep problems, depression, memory difficulties, and fatigue. Most people with PD first develop the disease after age 60, but about 10% experience onset before the age of 50. There is no cure for PD and currently available treatments are intended to relieve some symptoms.4 References Atassi N, et al. The PRO-ACT database: design, initial analyses, and predictive features.

HEIDELBERG, Germany I June 01, 2023 I Apogenix, a biopharmaceutical company developing next generation immunotherapeutics, announced today that new preclinical data were published in the leading peer-reviewed journal Frontiers in Immunology[1]. In the studies, Apogenix, in collaboration with the group from Professor Tim Illidge at the University of Manchester, UK, demonstrated the therapeutic benefits of the hexavalent CD40 agonist HERA-CD40L in models of prostate cancer refractory to anti-PD-1 therapies, both as monotherapy and in combination with radiotherapy. Importantly, HERA-CD40L was able to significantly reduce tumor growth through a threefold mechanism of action: it increased intratumoral T-cell concentration; modulated the tumor microenvironment (TME) towards a pro-inflammatory state; and reversed the macrophage balance from pro-tumor macrophages (tumor-associated macrophages; TAMs) to anti-tumor macrophages. Thomas Hoeger, PhD, CEO of Apogenix, said: “Immune checkpoint inhibitors have revolutionized cancer treatment, however, the overall response rate for all cancer types in patients is still below twenty percent. New immunotherapeutic strategies are required and with this next-generation HERA-ligand we investigated a potentially viable treatment option – as a monotherapy and in combination with radiotherapy – to improve cancer treatment outcomes.” The full article titled: “The CD40 agonist HERA-CD40L results in enhanced activation of antigen presenting cells, promoting an anti-tumor effect alone and in combination with radiotherapy” can be accessed here. HERA-CD40L is a novel molecule from Apogenix’ platform of hexavalent Tumor Necrosis Factor Receptor Superfamily (TNFRSF) agonists. CD40L is a key regulator of the immune system. The CD40-CD40L immune axis is primarily linked to B cells and is important for sustained antibody production, antibody class switching, and the production of memory B cells. Due to its characteristic of bridging the transition from innate immunity to the initiation of adaptive immunity, CD40 represents a very attractive target for drug development. About Apogenix Apogenix is a private company developing innovative immunotherapeutics for the treatment of cancer and viral infections, such as COVID-19. The company’s pipeline of immunotherapy drug candidates targets different tumor necrosis factor receptor (TNFR) superfamily-dependent signaling pathways in order to restore the anti-tumor immune response in cancer patients and reduce lymphopenia and inflammatory cell death in patients with viral infections. Checkpoint inhibitor asunercept, the company’s lead immunotherapy candidate, is in late-stage clinical development for COVID-19 and glioblastoma with PRIME (PRIority MEdicines) designation by the European Medicines Agency for the treatment of glioblastoma. Based on its proprietary technology platform for the construction of novel TNF superfamily receptor agonists, Apogenix develops CD40 and GITR receptor agonists for cancer immunotherapy. The TRAIL receptor agonist program was out licensed to AbbVie and is currently in clinical phase I trials. About Apogenix’ TNF Receptor Superfamily Agonists (HERA-Ligands) Apogenix has developed a proprietary technology platform for the construction of novel TNF receptor superfamily agonists (HERA-ligands). By stimulating different TNFR signaling pathways, these HERA-ligands can increase the anti-tumor immune response. The specific molecular structure of Apogenix’ HERA-ligands induces a well-defined clustering of functional TNF receptors on the surface of target immune cells. In contrast to agonistic antibodies, Apogenix’ fusion proteins are pure agonists whose potent signaling capacity is independent of secondary Fcγ receptor-mediated crosslinking. In addition, HERA-ligands cause neither antibody-dependent cellular cytotoxicity nor complement-dependent cytotoxicity and exhibit a favorable shorter half-life than antibodies. It is therefore expected that HERA-ligands will cause less side effects in clinical development. [1] https://doi.org/10.3389/fimmu.2023.1160116
